Co‐incubation experiments of spleen non‐lymphocyte layer cells before and after training with fluorescently labeled tumor cells, followed by flow cytometry analysis of CD11b+ cell phagocytosis efficiency, revealed that the ability of CD11b+ cells to phagocytose tumor cells was significantly higher after KK2DP7 training compared to the untrained group (Figure 6n). Here, ITGAM is linked to neoplasm.
